It is apparent that a very simpleand servhe outer rectangular portion of the iceable type of expansiblescreen has been provided which is so constructed that it will holditself in binding or tight engagement with the window casing and andwill adjust itself to variations in size of the windows.

Further, it will be seen that no additional fastening means whatsoeverare required, but that the expansible screen is so constructed that itautomatically locks itself in place against dislodgment.

It will be seen, therefore, that a very sim ple type of expansiblescreen has been provided which although having the characteristicsenumerated above is nevertheless free from any complicated structure orany construction which would mar its attractive appearance.

Although the invention has been described in considerable detail, suchdescription is intended as illustrative rather than limitin as theinvention may be variously embodie and as the scope of such invention isto be determined as claimed.

I claim:

1. An expansible screen comprising an inner rectangular framechannel-shaped in cross section, a wire mesh member carried by saidframe and secured to the intermediate wall thereof, an outer frameformed of channel sections telescopically receiving said inner frame,and springs interposed between said frames, said outer frame beingcomposite and having its parts telescopically related.

2. An expansible screen comprising an inner rectangular framechannel-shaped in cross-section, a wire mesh member carried by saidframe and secured to the intermediate wall thereof, an outer frameformed of channel sections telescopically receiving said inner frame,and springs interposed between said frames, said second frame beingformed of corner portions and straight sections between the cornerportions and telescopically fitted to said corner portions.

3. An expansible screen for automobile windows comprising a rigid innerframe channel-shaped in cross-section, a wire mesh stretched across saidframe and secured to the intermediate wall thereof, an outer frameformed of channel shaped corner portions and channel straight portionstelescopically related to said corner portions, said outer frametelescopically holding and surrounding said inner frame, springsinterposed be tween said inner and outer frames, and clips carried bysaid outer frame and adapted to lock said outer frame to a windowcasing.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in the county of Milwaukeeand State of Wisconsin.
